Located on the Potomac River just across from Washington, D.C., Alexandria is one town that can truly boast "George Washington slept here."His family home was 10 miles away in Mount Vernon, but our first president had close ties to Alexandria, Va., a seaport town founded in 1749. He had a townhouse here, drilled his first troops in Market Square in 1754, had a pew at Christ Episcopal Church and had both business and social activities in Alexandria.
